Abstract. Metallurgical testing is the most essential part of any mineral processing flowsheet development. Its objectives must therefore be clearly defined. These are discussed together with the importance of the choice of the samples required for the test program. Rather than describing testing procedures, stress is laid on how the test ...

The current study evaluates the RM processing for Al, Fe, Ti, and Sc & Ga extraction with simultaneous recovery of high-purity products. Direct sulfuric acid baking of red mud at 300 °C resulted in the dissolution of Fe (51%), Ti (65%), Al (89%), and Sc (51%) by subsequent water leaching. The entrainment of impurities (Fe and Al) with Ti ...

The bauxite ore contains aluminum trihydrate (Al (OH) 3 ). Alumina refining produces alumina (Al 2 O 3) from the bauxite ore, by exploiting the reversible reaction of the Bayer process 1–3 : The reaction is firstly driven in the sodium aluminate (NaAlO 2) direction by the addition of caustic soda (NaOH) to bauxite.

It has been said that gold was one of the first metals to be mined. As deposits with free, coarse gold were depleted and the volume of mining increased, process flowsheet design became more and more complicated. Gravity was the first method developed to recover gold from ore. But, currently there are very few deposits left that contain ores ...
